Questionnaire Results and Analysis - Christos

The questionnaire survey contacted had 4 objectives which were defined under the post "Spec. Requirements / Design Questionnaire". This section summarizes the outcomes of this survey on the various issues the elderly encounter with during their shopping.

1. To identify the problems encountered by the elderly while grocery shopping - Related questions: 1,2,8,11,14
2. To assess the familiarity with various technologies - Related questions: 3,4,5,6,7
3. To define measures of improvement - Related questions: Most of the questions
   
4. To identify age bias disabilities - Related questions: 13,14
   

In order to contrsuct some results to what level the e-trolley should be technologically advanced the personas were asked questions related to the type of technology they are familiar with.

Question 3 asks, "Do you have a computer at home?" .Both personas answered that they do have one. This indicates that at least the personas are either using a computer or someone else in the house is using it.
Question 4, "How often do you use the computer?", persona Ingrid Pollard has given the answer "I don't" while persona John Goldfinger answered "I use it often".
This indicates that we are obviously dealing with a target audience that has either never or barely used a computer before or the other extreme where they have actually been using one due to some circumstances(due to their jobs,children).
On question 5 the personas were asked to select a list of computer programs they are familiar with. Persona John Goldfinger has listed the following: 1. Web Browser (e.g. Firefox, Internet Explorer) 2. Word Processor (e.g. Open Office, Microsoft Word) 3. Slideshow (e.g. Photo Album, Picture Viewer) 5. E-mail (e.g. Outlook, Thunderbird) . This shows that the personas that are using a computer are familiar with the basic tools for doing a variety of tasks. From this we can conclude to the fact that at least this portion of the population has encountered with the most known user interfaces in the market.This is something that we need to take into consideration during the design stage of the product.

Questions 6 and 7 ask the personas if they have in their possession a mobile and if so its'brand. Both personas have answered "Yes" indicating that they have both encountered with mobile interfaces before. In the case of persona Ingrid Pollard the use of mobile is restricted in just making phone calls whereas John Goldfinger uses his mobile for taking pictures,sending sms etc. We can conclude once again that the target audience varies in skills when it comes to mobile devices.The fact though that a number of those have probably used a mobile somehow is at least a good sign when it comes down to designing the product.

Questions 13 and 14 aimed to discover what kind of disabilities are common and in what way the design of the system can be adjusted in order to avoid any dissapointments.
Ingrid has complaint for back pains which has direct affect to how long she can stand or walk each time. John had a leg operation recently and his doctor adviced him not to stress his leg. Both our personas have some sort of related problems that have to do with walking. Since shopping involves walking long distances and carrying heavy loads it is then e-trolley's main priority to reduce the amount of shopping time by estimating and suggesting faster routes. Wondering in a store trying to figure out where an item is kept is both annoying and tiring. For the elderly is an another burden to the many more they already have.
